SV-45169r1_rule The .rhosts file must not be supported in PAM.

Vulnerability discussion

.rhosts files are used to specify a list of hosts permitted remote access to a particular account without authenticating. The use of such a mechanism defeats strong identification and authentication requirements.

Check content

Check the PAM configuration for rhosts_auth. Example: # grep rhosts_auth /etc/pam.d/* If a rhosts_auth entry is found, this is a finding.

Fix text

Edit the file(s) in /etc/pam.d referencing the rhosts_auth module, and remove the references to the rhosts_auth module.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
